The idea behind the Tampa Women's Club charity event was simple. For $20, someone could buy a flute of champagne and a chance to win a one-carat, $5,000 diamond.

Organizers of the Saturday event placed $10 cubic zirconia stones in the bottom of 399 of the 400 champagne glasses. The prized diamond, donated by Continental Wholesale Diamonds, was placed in the last.

The problem for Miriam Tucker, 80, is that she accidentally swallowed it.

Tucker told local news media that she didn't want to put her finger in the champagne, so she drank a bit. While laughing with women at the table, she realized she swallowed it.

Embarrassed, she had to tell jewelers who were frantically searching for the winner.

Already scheduled for a colonoscopy on Monday, she had a doctor recover the jewel.
